I just fixed an ipod video with this problem by replacing headphone jack. I just can't figure out why headphone jack had anything to do with that. Songs always stuck at 0:00 while jack was attached but they played without it. I even tried the same jack on two various logic boards and problem was there too so I ruled out logic board and software cockup. Hard drive also was faultless...I previously scanned it for bad sectors and none was found.
